Manage Direct Debit Secured payment

Manage Direct Debit Secured payments for your customers.

If you are using payment type sepa-direct-debit-secured, note that this method is now deprecated. It is currently supported but there are no further developments planned for them.

If you want to access the relevant documentation, see (Deprecated) Unzer Direct Debit Secured.

After the successful authorize transaction, you must perform additional operations on the payment resource. Some of the important ones are described in the following section.

For a full reference of managing payments, go to relevant server-side integration documentation page: Manage API resources (direct API calls), Manage API resources (PHP SDK), or Manage API resources (Java SDK).

Reauthorize the transaction

The authorization patch request changes a previously authorized amount of a purchase with Unzer invoice, Unzer Installment, and Direct Debit Secured methods. It contains the amount value. The customer information from the referenced authorization request is used for another internal risk check. Within a few seconds a response is returned:

Declined: The new amount was not accepted. The originally authorized amount is still valid.

Accepted: The previous amount of authorization is updated and the new one is reserved for charge.

Full charge

Making a charge transaction signals you are shipping goods to your customer while capturing the respective order amount.

The charge call is a crucial API call that initiates the process for payout of the charged amount to the merchant and the deduction of the money from the customer’s bank account.

POST: https://api.unzer.com/v1/payments/s-pay-1/charges

{
}

$unzer = new Unzer('s-priv-xxxxxxxxxx');

$chargeInstance = new Charge();
$chargeTransaction = $unzer->performChargeOnPayment('s-pay-1', $chargeInstance);

Unzer unzer = new Unzer("s-priv-xxxxxxxxxx");
Charge charge = unzer.chargeAuthorization("s-pay-1");

Provide shipping information

To allow Unzer to track the customer’s order, you can provide shipping information in your charges request. Based on the information provided, the customer’s payment period will only start when the order has reached your customer.

Shipping information can be provided in the following fields:

Parameter	Type	Description
`deliveryTrackingId` (optional)	string	Tracking ID of the selected delivery service provider for the delivery to the customer.
`deliveryService` (optional)	string	Delivery service provider used for ship the goods to your customer (such as, DHL, UPS, and Hermes)

        }
  }
}

$unzer = new Unzer('s-priv-xxxxxxxxxx');

$shipping = (new ShippingData())
    ->setDeliveryTrackingId('0034043423434443222')
    ->setReturnTrackingId('00123434286851877897')

$chargeInstance = new Charge();
$chargeInstance->setShipping($shipping);

$chargeTransaction = $unzer->performChargeOnPayment('s-pay-1', $chargeInstance);

Partial charge

If you ship an order in multiple steps, you can make make a partial charge for each part you want to ship.

The charge call is a crucial API call that initiates the process for payout of the charged amount to the merchant and the deduction of the money from the customer’s bank account.

}

You should also provide the shipping information as previously explained in the full charge section.

Cancel before charge (reversal)

If the customer cancels an order completely before you ship the goods or if the goods are not available in stock, you must cancel the order by initializing a reversal.

If the customer is not cancelling the order completely, you don’t need a reversal transaction. Only charge the remaining items as soon as you ship it.

POST: https://api.unzer.com/v1/payments/s-cnl-1/authorize/cancels

}

$unzer = new Unzer('s-priv-xxxxxxxxxx');

Dunning delay (refund announcement)

This is the prior step required for refund (issued charge cancellation). The merchant announces the charge cancellation, and the fulfillment date will be moved accordingly.

Typical events are customer phone calls or printing return stickers (RMA). They help to prevent unjustified dunning of customers.

Cancel after charge (refund)

In case you already charged a payment for an order that the customer wants to cancel/return, you can refund it up to the charged amount. To do this you have to make a cancels transaction on the respective paymentId.

}

The charges initialized after the authorize are actual payments and can be refunded by canceling them.
